Yes, I agree... But it's even more complicated, because peering exchanges are only available in meaningful numbers in Europe and some countries around it. Also paths can be QoSed depending on many parameters, costs and deals. We built a software that optimized routing based on cost depending on the 95th percentile usage, channel quality and some other parameters. In Asia, South America (really shitty place for internet infra) and North America the conditions are different.

But Youtube did indeed built a great CDN, coupled with control of the end user video player made the best video on demand platform by far.
